Kennametal 2599511 Grooving Insert NRP3031 KC5010 Carbide

Product Description

The KENNAMETAL 2599511 is a solid carbide grooving insert designed for precision groove turning operations on CNC lathes and turning centers. This insert carries the KC5010 manufacturer grade and features a physical vapor deposition (PVD)-applied TiAlN coating for improved wear resistance and tool life in demanding cutting conditions. The insert has a left-hand orientation with a 1.58 mm cutting width and a maximum depth of cut of 2.39 mm. The full-radius geometry with a 0.79 mm corner radius and a 5-degree positive rake angle promote clean chip flow and reduced cutting forces. Machinists and CNC operators install this insert in compatible Top Notch series toolholders.

This insert is suited for grooving, parting, and profiling operations on a range of workpiece materials. The KC5010 grade with TiAlN coating performs well in steel, cast iron, and high-temperature alloy applications where heat resistance and edge integrity are critical. It is used in production turning environments, including both job shops and high-volume manufacturing. The metric-dimensioned NRP style and 3031 insert size place it in the Top Notch series, a widely used platform for external and internal grooving work.

Key Features

• Solid carbide construction with PVD TiAlN coating for heat and wear resistance
• Left-hand cutting orientation
• 1.58 mm cutting width with full radius geometry
• 0.79 mm corner radius for consistent groove profile
• 5-degree positive rake angle reduces cutting forces and promotes chip evacuation
• KC5010 grade rated for C3 and C4 material groups

Compatibility

Designed for use in Top Notch series grooving toolholders that accept NRP-style inserts in the 3031 insert size. Confirm toolholder seat geometry and insert size designation before installation.

Installation Notes

This insert is installed and replaced by a CNC machinist or toolroom technician. Power down and lock out the machine before changing inserts. Use proper insert seating tools and verify the insert is fully seated and clamped before resuming cutting operations. Follow the toolholder manufacturer guidelines for clamp torque and insert retention to avoid insert movement during cutting.
